Additionally, learning about the common causes of knee pain helps you know what could be causing yours and what your treatment options are. Once you’ve uncovered the cause of your knee pain, it’s that much easier to treat and then prevent in the future. Here’s what you need to know about some of the most common causes of knee pain and how they can be both treated and prevented. 

What Causes Knee Pain?

There are many different common causes of knee pain that vary based on the part of the structure of your knee that is affected. In order to understand what causes knee pain, it’s helpful to know a bit about the structure of the knee itself.

Your knee is composed of three bones: the lower thighbone, the upper shinbone, and your kneecap, also known as your patella. These are held together with ligaments and tendons while cartilage helps to both cushion and to stabilize your bones under the kneecap. If any of these parts of your knee have been damaged, diseased, or impacted in any way, it can lead to knee pain. The severity of your knee pain will depend on the severity of the cause. 

Symptoms Of Knee Pain

Depending on which of the common causes of knee pain is the culprit of your own knee pain, the signs and symptoms associated with it will vary, due to the location of your pain and its severity.

Some of the common symptoms of knee pain include:

• Redness
• Warmth to the touch
• Swelling
• Stiffness
• Weakness
• Instability
• Popping/crunching noises
• Inability to straighten the knee

While some symptoms of knee pain are bearable and not cause for too much concern, there are instances where you should contact a doctor as soon as possible. You should call your doctor sooner than later is:

• You can’t bear weight on your knee.
• The pain is severe, even without weight on it.

Common Causes Of Knee Pain

The common causes of knee pain range in severity from a simple sprain to an injury. Here are some of the most common causes of knee pain that people experience.

• Arthritis

This includes gout, lupus, osteoarthritis, and rheumatoid arthritis.

• Infection in the knee joint
• Infection in the bones of the knee
• Baker cysts

These are swellings full of fluid behind your knee that can happen with inflammation from other common causes of knee pain, such as arthritis. 

• Osgood-Schlatter disease

This most commonly occurs in teenagers, when your bones are still changing. Over-exercising can cause a bump below the knee that comes and goes over time. 

• Bursitis

Your bursa is a sac of fluid under your joint that prevents friction during movement. Overuse can cause swelling and pain.

• Dislocation

This is when your kneecap slides out of its location.

• Fracture
• Strain or sprain
• Torn cartilage
• Torn ligament
• Patellofemoral syndrome

This is caused by muscle tightness, imbalance, and alignment problems, that doesn’t occur as a result of an injury.
